To all whom it may concern,.-

Be it known that I, J ULIUs OTTO OBER- MAIER, a citizen of the German Empire, residing at Lambrecht, Bavaria, Germany, have invented certain new and usefullmprovements in Apparatus for Treating Fibers, Yarns, and Weavings of all Kinds, of which the following is a specification.

The object of this invention is the dyeing, Washing, and so forth, of textile fibers, yarns, and weavings of all kinds by the continuous circulation of the liquids ordinarily employed for these purposes through the matters to be so treated.

Figure 1 is a sectional elevation of an apparatus for effecting these objects and embodying my invention. Figs. 2, 3, 4, 5, 6, and 7 are merely modifications, in all of which figures the principle is unaltered.

The apparatus consists of two concentric perforated cylinders, C M, the inner or smaller one, O, being open below. The spaces between these cylinders serve for the reception of the textile material to be treated, which is piled upin equally-divided layers. The bottom is closed. The top is closed by means of a lid, P, which bymeans oi' a screw presses this lid more or less down upon the material to be dyed, in which condition it remains during this operation, it being by this means firmly pressed and immovable. The screwing-down arrangements are marked by the letters h, p, f, and F. The cylinder M having been filled with the text-ile matter it is hoisted by any suitable means and placed in the vat A, in which the dye has been previously prepared, and,if so desired,is heated by the introduction of steam. Beneath this cylinder is the inlet N of a continuous -acting suction and force pump, G, fixed beneath the vat A. This pump is set in motion and they liquid dye is drawn off from the vat A and forced into the small perforated cylinder O, and from thence through thelayers of textile matter in the cylinder M that are to be dyed. The liquid then passes through the outer `cylinder (which is also perforated) into the vat A and the process recommences.

K is a valve at the bottom of the vat. His a drawing-off tap. R are heating-tubes.

When several operations are to be perplaced in each of these successively till the operations of boiling, dyeing, mordanting, rinsing, Src., are performed, as desired. By this means time is saved, and the contents of the different vessels for effecting these objects can be used for a longer period. This arrangement is subject to modifications according to the nature ofthe matters to be so treated, without, however, departing from the principle of action.

In Fig. 2 the cylinders C, mounted on the perforated upper plate of the chamber D, are closed by a perforated and adjustable lid, and the pump G, Fig. l, or some equivalent, forces the liquid (intended to act on the textile matter) through the pipe a, whence it enters the cylinders at the bottom and makes its exit above. The chamber E beneath the intermediate one, D, is intended for the reception of other materials-such as wool, yarn, Src. This is closed by the perforated lid e.

In Fig. 3 the liquid being forced in at the bottom it makes its eXit at the top b, as shown by the dotted arrows; or if the liquid is forced in at d it spreads first in the upper chamber above the perforated plate F, and then passes through the material piled up between F and E and runs off at the bottom, as shown by the solid arrows.

In Fig. 4 the cylinder C is not perforated, but has openings n, through which the liquid is forced up by the pipe a and passes through the perforated bottom of the cylinder M into thespace E. The liquid then rises by pressure from the space E and passes through the material and flows out at the top through the perforated lid D.

In Fig. 5 the liquid is forced through the lateral tube d, Where it enters (after passing through the material in the cylinder M) into the cylinder C, where it flows off.

The cylinders .M M being filled with textile matters which are pressed closely together, the pump G is then set in motion, andthe dyeing-liquid being sucked lup from Ithe Vat or reservoir A is then forced through a2 to C2 and flows through the material in the- ,cylinder M1; but as the motion of the pumpV .reduces the pressure oi' the air in the cylinder C the liquid inA passes rapidly through the sides of the cylinder M', as well as through the layer of material, and returns by a to the 2-5 pump, whence it is again sucked and forced,

.as before described, so producing a continuous circulating action of the liquid. l

What I claim is- In an apparatus for treating textile fibers, 8m., the combination, with the Vat, of the stationary perforated cylinder M, the interior stationary perforated cylinder, C, and the pump having connections with the vat and y the central cylinder, su bstantially as described. 3

In testimony that I claim the foregoing as my invention I have signed my name in presence vof two subscribing witnesses.
